203994 divided by 13 
Let's see how many times 13 fits into 203994.

Going ahead to step 1:
If we divide 2 by 13, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 13

Moving on to step 2:
13 goes into 20 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 13 from 20 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 13

Moving on to step 3:
13 can be fit into 73 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 65 away from 73, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 13

Going ahead to step 4:
The number 13 fits into 89 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we subtract 78 from 89, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 13

Going ahead to step 5:
119 divided by 13 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1569.0
Subtract 117 from 119 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 13

On to step 6:
If we divide 24 by 13, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 15691.0
The remainder is 11 after subtracting 13 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 15691.8
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15691.84
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 15691.846
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 13 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 15691.8461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15691.84615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 13, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 15691.846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
110 divided by 13 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 15691.8461538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 15691.84615384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 15691.84615384 with a remaining 8e-09.
